: pcmforless tune, now car won't start

what am i missing here, i ordered the new pcm, installed it (with the - off the battery), now the car starts, immediately shuts off, and i get a message on my DIC saying starting disabled - remove key.

sounds like a VATS issue ... have you contacted the place you got the PCM from yet?

It acts just like mine did the first time I tried to use the second key. I had to program it but then I had one key that did work. You probably don't so I'm not sure how you would do it without a working key. You can program a key yourself ( put a known good key in turn it to on (don,t start ) turn it off put the new key in and tun it on within 10 sec. done )

i THINK i figured it out, apparently there's a security relearn instruction sheet that is supposed to be included in the box, but wasn't.

that makes sense... probably takes a half hour ... 3 ten minute sessions to program your key to the pcm

i hope it pans out or i might go on a self-rampage
